/*
Scanf.c: 1. Shows how to write a function to input data.
         2. Shows how to retrieve a string.
         3. Shows how to use C function: sscanf, or just use Scanf().
         ** MSC 6.0 cannot use Scanf(), because don't support function vsscanf()
        
Compiler: BC++ 3.1,
          Turbo C++ 1.01 (3.01)

Compile mode: Large

Project: Scanf.C
         ..\..\Lib\uPAC5000.lib

Hordware: uPAC-5000

Note
    The COM1 of £gPAC-5000 is the standard I/O port. Before calling the InstallCom(1,.. ) whitin user's program, 
    user can use the following member functions to send/receive data to/from COM1.
        Kbhit()
        Getch()
        Putch()
        Print()
        Scanf()
   
    All member functions do not work after Installcom(1,.. ) is called. It must use IsCom(1,.. ), ToCom(1,.. ), ReadCom(1,.. )
    to send/receive data to/from COM1. These functions work until RestoreCom(1,.. ) is called.
